Yes I have one.
It sounds good.
Build quality great, very solid.
Does not do lossless formats, does wma, mp3, ogg, wav
The remote lcd is very small and hard to read the tiny writing.
Support is good and firmware is being updated frequently - a good sign that they are on the case.
Connects via USB2 either via the dock or via a mini-dock
Has line-in, line-out, usb & power connections on both docks.
Appears as a hard-disk in Windows so you can just drag & drop like any internal/external drive.
You cannot listen to it when it's connected via USB except of course via the PC (it's a standard drive in that respect).
Earphones usual standard for these things would recommend better set.
Does that help?
In my opinion it make the Ipod design look plasticky & dated - I won't knock Ipods as I've never used one so I cannot compare the two.
You'll find mentions of problems with remotes but this is supposedly all fixed now - no problems with mine or my mates one.
You have to be prepared to say "I have a Cowon" and have non descript earphones rather than "Look I've got white earphones and an Ipod - mug me please!"
